Stuparich,'San Francisco, Calif.. .11i'ppl'ieatiq'liJune ls, 41933, serial No. 674,412 if j claims." (c1. 1r- 29) My invention relates to a new and useful apparatus for use in-connectionwitha process'for sprz'iyingV a coloring Vcornpound- 'for lborderin photographic mounts and-the like.

In the art'of spraying'and decorating photographic mounts,v it has'previously been found very difI-lcult to properly spray coloring or tinting fluidsupon the mountA material, and 'to secure clearly deiined border lines, that is, to successffully block out certainlsections of the mount while other sections thereof are being sprayed and tinted.

The material in general use for this purpose is more or less spongy, and the surfaces to be sprayed are always more or less uneven, hence, the sprayed fiuid tends to run or spread to some extent, thus tending to produce wavy or irregular border lines between different shades of sprayed fluid, or along border lines bordering openings,

or marginal lines of the sprayed mounts.

The apparatus constituting the present invention tends to obviate these difficulties by the employment of a specially developed apparatus which not only effectively blocks out the areas of the mounts to be left untouched by the spraying fluid, but also provides a means for the irnmediate absorption of any excess fluid by capillary action, which iiuid may be sprayed upon the material without in any way aiecting the perfection of the denition of the border lines acquired in this manner.

The principal object of the invention is to provide a simple and elcient apparatus of the character disclosed, to enable the operator to effectually and quickly block out certain sections of the photographic mount while the spraying operation is carried on, so that the mount or mounts may be thoroughly and artistically decorated or tinted; and so that the finished mounts will have clearly and perfectly defined contrasting border lines.

A further object of the invention is to provide an improved spraying apparatus which enables the operator to effectively spray large numbers of mounts with a minimum of labor and time, the nished mounts thus sprayed being perfect in color and border line definition.

A still further object of the invention is to so simplify the spraying operation and the number of parts of material utilized in producing the I' mounts, that the cost of the same is kept at a minimum.

Other objects and advantages of the invention become apparent with reference to the subjoined specication and the accompanying two sheets z of drawings in which:-

f `Figure 1 is a perspective View illustrating my improved method of mounting and blocking the mount while it is being sprayed by the use of the usual spraying apparatus;

Figure 2-is a transverse section taken through the base block, the mount and the apparatus utilized in conjunction with the spraying operation, said apparatus fitting into the base block as shown, and having its beveled edge overlapping the inner edges of the mount, to eectively block off a border surrounding the picture opening of the mount; the section being indicated by the section line 2 2 in Figure l;

Figure 3 is a perspective view per se of the blocking and mount retaining unit;

Figure 4 is a side elevation illustrating a set of rolls for rolling and egg shelling the finished mount;

Figure 5 is a front elevation illustrating the finished and bordered mount section before it is applied to the foundation; and

Figure 6 is a front elevation illustrating the completed mount after it has been beveled and mounted on the foundation or backing.

In carrying out the process constituting the present invention, it is to be understood that it is the primary object to provide a simple yet very efficient method of producing an artistically designed photographic mount of exceptionally simple character and one that when properly sprayed, bordered and egg shelled, presents a most pleasing appearance due to the delicate colors ernployed and the sharpness of definition secured between the color work and the borders thereof.

The special process and apparatus employed in this art, consists of first providing blanks 10 of the proper size and texture, and punching the same to form the usual picture opening 11, as clearly disclosed in Figures 2, 5 and 6 of the drawings.

These blanks are then placed upon a base block 12 in which is provided an opening 13 of the same size as the openings ll-which openings are aligned for the reception of the blocking apparatus 14, Figures 1, 2 and 3.

This blocking apparatus embodies a depending section 15 made to fit snugly into the opening 13 in the base block 12, said section 15 being of metal and heavy enough to holdthe apparatus in place in the base block. A plate 16 is secured to the upper face of the section l5 and is held securely thereon by means of screws 1'7, Figure 2, the outer overhanging edges being beveled to a knife edge 18 and resting upon the mount blank 10 in close proximity to the opening 11 formed therein so that a border strip will be defined about the inner edges of the opening 11 when the product is completed.

A pad 19 of absorbent wicking material is provided and rests upon the plate 16, and a top clamp plate 2O rests upon said wicking, the whole being held securely together as a unit by means of a fixed bolt 21 having a knurled nut 22 mounted upon itsupper threaded end, so that the wicking may be removed and changed at will.

In Figure 1 the complete operation is shown,

the blank 10 being illustrated as held in place i by the blocking unit 14 with the spraying brush 23 in operation and spraying the liquid tinting material 24 upon the blank around the blocking unit.

The beveled section 18 of the plate 16 is held in close contact with the blank 10 due to the weight of the section 15, and this overhanging beveled section effectively seals a border section 25 entirely surrounding the picture opening Y1l thus providing a perfect fully white border in contrast to the sprayed or tinted section 24 surrounding this border section.

rEhe wick 19 due to capillary action, draws any excess luidY which may collect at the bevel edge'l upwardly on said bevel, and absorbs the same so that when the apparatus is removed from the mount the sprayed material will not be smeared and the border will thus be perfectly defined.

After the blanks have been sprayed, they are inserted sprayed side up between a set of pressing rollers 26 and 27, together with a section of abrasive material 28 which produces a stippled egg shell effect, and at the same time removes any wrinkles which may remain in the nished b1anks-the said iinished blanks are then pasted at their upper edges 29 to suitable backing or foundation sheets 30 of a contrasting color.

I claim and desire to secure by Letters Patent of the United States the following:-

1. A device for use in spraying photographic mounts, said device including a plug adapted to enter into the opening in a mount, a plate provided with absorbent material and disposed upon said plug, said plate being of such size that it will overlap the edges of the said opening when said plug is entered therein, and means for clamping said plug and said plate together.

2. In a device for use in spraying photographic mounts, said device including a plug adapted to be seated in the opening in a mount, a plate disposed upon said plug and of such size that it will rest uponthe edges of the opening in the mount and dene a border therearound, said plate having a sharpened peripheral edge providing capillary means and absorbent material carried by said plate adjacent said peripheral edge.
